Red clothes look red because they REFLECT the red light, and absorb light of other colors.
If the temperature is increased the particles gain more kinetic energy or vibrate faster. This means that they move faster and take more space.
Answer:
ε = 6.617 V
Explanation:
We are given;
Number of turns; N = 40 turns
Diameter;D = 18cm = 0.18m
magnetic field; B = 0.65 T
Time;t = 0.1 s
The formula for the induced electric field(E.M.F) is given by;
ε = |-NAB/t|
A is area
ε is induced electric field
While N,B and t remain as earlier described.
Area = π(d²/4) = π(0.18²/4) = 0.02545
Thus;
ε = |-40 × 0.02545 × 0.65/0.1|
ε = 6.617 V
(we ignore the negative sign because we have to take the absolute value)
Metal
Explanation:
semiconductors are materials which have a conductivity between conductors (generally metals)
